Greetings again from Minnesota where it’s getting cold again. Below freezing last night, brrrrr!! But there ain’t no rest for the wicked, so let’s get back into some light painting techniques. This time I would like to talk a bit about Cold Cathodes.
A cold cathode is a tube of light that has a similar look to neon lights. It is brighter than a glow stick, and you can attach an on/off switch making them much more versatile in the field. You can find different kinds of these cold cathode tubes. They can be found at auto part stores, for in car light accents and under car lighting.
